I'm curious how you guys deal with dreaded "tartan creep?" I went out in my SWK heaviweight and an Aran sweater to do some hiking with my son the other day, and noticed that the kilt would "walk" up my legs in the front, under the sporran, exposing my legs to the cold. It got pretty annoying having to straighten things out so frequently. I was wearing some sort of knit, insulating boxers underneath which I think was the source of the problem. I thought that I might be froced to switch to bike shorts, which are a smoother surface....
